GAME.co.uk is the exclusive retail partner in the UK and Ireland for the Call of Duty 4: Modern Warfare Multiplayer Beta on Xbox 360, which will start on the 10th September 07 and not the 7th September 07 as previously stated.

We have a limited number of places reserved for our customers to participate in this Beta programme. All you need to do is pre-order Call of Duty 4 on Xbox 360 and we will email you your Activision Clearance Code and details on how you can participate. We recommend you hurry as places on the Call of Duty 4 Beta are limited and will be in extremely high demand. Please note: the Activision Clearance Codes will be emailed every Thursday until the Beta closes

The keys'll be available from Eurogamers tomorrow - keep an eye on the Giveaways sidebar! I'm sure there'll be a news story on the EG front page advertising it, too. First come, first served, as usual.

It's all quite exciting as it's the biggest giveaway we've done so far - shame it's for 360 and not PC, though.
